Event Study of Credit Rating Announcement in the Tokyo Stock Market

Michiko Miyamoto
Abstract— This research examines the market reaction to announcements of credit rating assignments for debt issued by Japanese companies before the subprime loan problem. In this study with Japanese companies, the market reacted positively with negative announcement. Stock prices seem to react before the information of rating changes is announced. Market participants seem to act on rumors of rating changes.

Index Terms— Event study, credit ratings, Tokyo stock market.
